I made a little test scene for using them for controlling wheels when vehicle follows path.

I did not find any previous examples of doing this so here is my solution:
When the length of the curve (actual length, not path length) and radius of the wheel are known, the rotation can be calculated based on Speed-curve that controls the vehicle motion.

I did not quite understand the logic of the rotation handling of this driver. Rotations are n * 10 degrees, so if I want to rotate object 90 degrees, the script must output 9. Thas why there is 36 in the expression above.
